- file RenderingWindow.h

- Description:
- This file contains exported routine prototypes that can be used to call
- the routines defined in RenderingWindow.c. These routines used to
- manage the windows displayed by the HTMLSample application.
-
- HTMLSample is an application illustrating how to use the new
- HTMLRenderingLib services found in Mac OS 9. HTMLRenderingLib
- is Apple's light-weight HTML rendering engine capable of
- displaying HTML files.
